Admesio:
A direct marketplace for publishers and advertisers

We built Admesio, a marketplace where app publishers create listings and advertisers browse them and get in touch directly. Admesio takes no commission on the deals they agree.

About the client
Digital advertising, where app makers and small publishers often sell their space through networks that decide who sees what.
What they needed
Give publishers a clear place to be found, and give advertisers a way to judge fit before they get in touch.
Where they were
Small app makers often have a real audience and no easy way to show it to advertisers. Ad networks sit in the middle, so publishers can have little say over who advertises and little sense of how the money is worked out.

The challenge

What was getting
in the way

Small app makers often have a real audience and no easy way to show it to advertisers. Ad networks sit in the middle, so publishers can have little say over who advertises and little sense of how the money is worked out.

Advertisers have the opposite problem. Finding a suitable placement can mean hunting through scattered sites and generic inventory, with little information about category or audience before the first message goes out.

  • Publishers stay hidden

    A useful app with a loyal audience can go unnoticed if no advertiser ever comes across it.

  • Blind searching

    Advertisers can lose hours looking for placements without clear signals about category or fit.

  • Too many middlemen

    When several platforms sit between the two sides, conversations slow down and decisions are harder to explain.

The solution

What
we built

  1. 01

    Publisher listings

    Publishers create a profile for their product with its category, positioning, audience context and available opportunities, so advertisers see the useful details first.

    Listing covers
    Category and audience
    Product types
    Apps, sites, AI tools
    Entry plan
    Free
  2. 02

    Advertiser discovery

    Advertisers browse listings by category and compare them using product context, which helps them narrow the field before starting a conversation.

  3. 03

    Direct connection paths

    Interested advertisers reach publishers directly. Sponsorships, promotions and custom deals are agreed and paid between the two parties, outside the platform.

    Business impact

    No app changes to begin

Before and after

How the work
changed

Finding advertisers

Before

Left to a network

Publishers usually hand their inventory to a network and have little contact with the brands behind the ads.

After

A listing they control

Publishers describe their product in their own listing and hear from advertisers browsing that category.

Finding placements

Before

Scattered searching

Advertisers usually piece together options from different sites, often with little context on each one.

After

One place to browse

Listings sit together by category, with product and audience context shown for each.

Setting up

Before

Technical integration

Ad networks commonly ask publishers to add an SDK to their app before anything can run.

After

Sign up and list

Admesio needs no SDK to begin. A publisher signs up, creates a profile and goes live in the marketplace.

  2. Advertisers

    Category-led discovery

    Fit can be judged up front

    Before: Blind searchAfter: Browsable listings

  3. Deals

    No deal commission

    Agreements stay with the two parties

    Admesio takes no commission from deals and does not process advertising payments, so terms stay between publisher and advertiser.

    Before: Network in betweenAfter: Direct talks

Trust and control

How we kept it
safe and reliable

  • 01

    No hold on deal money

    Advertising payments do not pass through Admesio. Publishers and advertisers settle them directly.

    Outside the platform
  • 02

    No code in the publisher's app

    Taking part does not require an SDK, so listing a product does not touch the app that users run.

    No SDK
  • 03

    Publisher says what appears

    The listing is written by the publisher, who decides which details and opportunities to show.

    Publisher-written

Faster delivery

Built on tested foundations
